Red Hat Linux release 6.0 (Hedwig)
Kernel 2.2.5-15 on an i686
On a dual PIII-500 system. Everything goes smooth and nice, but when I su - root it'll take about a literal minute before it's done. Very occasionally it will pause about 20 seconds before running a program as well. There's about half a gig of RAM, and enough hard disk space.
